Abstract
The purpose of the present study was to re-examine the construct validity of the Das-Naglieri Cognitive Assessment System Japanese Edition (CAS-J) with data from the standardization sample for the CAS-J (N=1,201), dividing the sample into 4 age groups: 5-7, 8-10, 11-13, and 14-17. Confirmatory factor analyses were conducted to compare 4 models: a 1-factor model, a 2-factor model [(PA)(SS)], a 3-factor model [PA(SS)], and a 4-factor model [PASS]. The results from a Χ2 test were the smallest at all 4 age groups on a 4-factor model. Indices suggested that the 4-factor PASS model was best/better fit to the CAS-J standardization data in all 4 age groups. It was concluded that the PASS theory of intelligence was confirmed in the Japanese standardization sample. The findings also provided further information about the construct validity of the CAS-J. The present results suggest that the PASS theory of intelligence may be a useful model for Japanese children and adolescents.
